Known Issue(s)

? SQ-Drive - Loss of power or unplugging a device during multi-track or stereo record may result in the current recording being lost.

? Audio not passing when attempting to load an unavailable add-on -When loading a show which uses an add-on not available in the installed firmware, a default processing unit will be loaded, but the audio will not pass until the processing has been switched out. This can happen when a show saved on the newer firmware is loaded into an SQ running older firmware.

? Incorrect sync with MixPad when Mixer Config is changed - Adjusting the Mixer Config on the desk will cause issues in the SQ-MixPad I/O Patch screen until the app has been disconnected and reconnected. For this reason, SQ-MixPad should only be connected after Mixer Config settings have been applied at the desk.

? Loaded MixPad Offline show not copied when updating on PC/Mac - When updating the SQ MixPad app on a PC or Mac, the show loaded in Offline mode is not automatically copied across to the new version. Best practice is to store the currently loaded show before updating, then install the new version of MixPad and recall the show being worked on before uninstalling the older version.
